Warning messages are not shown after I used a specific theme

I have used "Texture" Theme by EltonCris, but it now all the warning messages are not shown, just a bright highlights on the fields which have the problem.

This makes the form submitter wonder what the problem really is, because I have customized some warning messages to keep the causes of not accepting the forms clearer.

This issue can be resolved by injecting the below custom css code:

.form-line-error .form-error-message {

    background-color: #ff3200;

    clear: both;

    float: none;

    display: block!important;

}

After injecting the custom css code, all the warning messages will be display properly:
